mSystems, 2023 Photosynthesis (PS) in purple non-Sulfur bacteria (PNSB) is strictly controlled to avoid energy consumption and to prevent oxidative stress when oxygen is present. PpsR, a transcriptional repressor encoded in the photosynthesis gene cluster (PGC), is one

HP1: Heterochromatin binding proteins working the genome [PDF]
Epigenetics, 2010 Heterochromatin Protein 1 (HP1) is a transcriptional repressor that directly binds to the methylated lysine 9 residue of histone H3 (H3K9me), which is a hallmark histone modification for transcriptionally silenced heterochromatin. Studies of homologs in different organisms have provided significant insight into the function of HP1 and the role of ...

Roles of TIF1β in Leukemic Stem Cell Through SETDB1‐Dependent and Independent Mechanisms
Cancer Science, EarlyView.In leukemic stem cell, BCR::ABL cooperates with TIF1β to open chromatin at oncogenes and close chromatin at differentiation regulators, driving leukemic reprogramming. In TIF1β‐deficient stem cell, the loss of TIF1β inverts this balance, showing closed chromatin at oncogenes and open chromatin at differentiation regulators.

Wealth inequality and epidemics in the Republic of Venice (1400–1800)
The Economic History Review, EarlyView.Abstract This article analyses wealth inequality in the Republic of Venice during 1400–1800. The availability of a large database of homogeneous inequality measurements allows us to produce the most in‐depth study of the factors affecting inequality at the local level available thus far for any preindustrial society.

Plant, Cell &Environment, EarlyView.ABSTRACT Global warming impacts several aspects of plant physiology, with important negative effects on crop yield and production of secondary metabolites, such as anthocyanins. The anthocyanin content of vegetables and fruits has attracted public interest in the last two decades due to its health benefits, leading to the development of novel ...

Hybrid kernels integrating genomic and multispectral data improve wheat genomic prediction accuracy
The Plant Genome, Volume 19, Issue 1, March 2026.Abstract Genomic selection (GS) is transforming plant breeding by enabling more accurate and efficient identification of superior genotypes. However, its practical implementation remains challenging, as achieving high prediction accuracy is critical for its success. Several factors—including sample size, the degree of relatedness among individuals, and

Mammalian HP1 Isoforms Have Specific Roles in Heterochromatin Structure and Organization
Cell Reports, 2017 HP1 is a structural component of heterochromatin. Mammalian HP1 isoforms HP1α, HP1β, and HP1γ play different roles in genome stability, but their precise role in heterochromatin structure is unclear.

DYRK1A phoshorylates histone H3 to differentially regulate the binding of HP1 isoforms and antagonize HP1‐mediated transcriptional repression [PDF]
EMBO reports, 2014 Heterochromatin protein 1 (HP1) proteins are chromatin-bound transcriptional regulators. While their chromodomain binds histone H3 methylated on lysine 9, their chromoshadow domain associates with the H3 histone fold in a region involved in chromatin remodeling.
